Does anyone get dizzy when you stretch out your torso/back? If I stand up really straight to stretch out my torso, even if I've already been standing up for a long time, I get lightheaded and spotty. It happens even if I don't raise my arms above my head - it's just the stretching out of my torso area.

I realize it sounds just like positional hypotension, but it never happens to me when I go from laying to sitting or sitting to standing. It's only the stretching.
